Question

【题目】—Where are Jim and Tom? Their mother is looking for them.

—They _____ over there.

A. runB. runsC. are runningD. running

Answer 1

【答案】C

【解析】

句意：——吉姆和汤姆在哪里？他们的母亲在找他们。——他们正在那边跑。A. run动词原形；B. runs一般现在时态的第三人称单数形式；C. are running 现在进行时态形式；D. running动名词或现在分词。根据上句可知本句应为现在进行时，因run为重读闭音节动词，应双写最后一个字母再加ing，此空故填are running，故选C。
